This Ordovician gastropod is like no others that I have found. Any knowledgeable members able to educate me?? Maybe a strange maclurite?? Love the hollow crystalline interior.

Just got back from a trip to Forbes, NSW a couple of days ago. Found some great stuff! But after that we checked out a site mentioned very vaguely in an old paper and were pretty successful! The site which is located near Parkes, NSW has Late Ordovician trilobites and other fauna. From what I can gather most of the species from the site are undescribed(?). Anyway, here are a few of my finds, maybe @piranha could help out with some ID's. Oh and I haven't finished prepping these specimens, but I'll post them when I have, although it may be a while since my airscribe has decided to break Crinoid Undescribed calymenid Unidentified trilobite cephalon Another no ID trilobite cephalon. Halfway through prep... continued...

Locally, I find quite a few large cephalopods. Here is an example: Unfortunately this specimen was deteriorated. and I collected only it's exposed siphuncle. After gluing it back together, I noticed definite narrowings that I do not understand. Other siphuncles I have found have raised areas on them, not narrowings. Any ideas on this anatomical aspect??? Here is another cephalopod I found that day. Love the crystals inside.

Was digging around in some boxes and found this specimen... it has a decent number of species on it! Although its nothing compared to another plate found at the site by some friends. We were going to split it but decided not to. Ended up having a couple hundred individual graptolites inside... but anyway! Sorry about the horrible pic as per usual. Early Ordovician (Bendigonian Stage) Bendigonian Formation, near Bendigo, VIC Australia.

Hi everyone, I’m very much an amateur and late new starter. This is my first enquiry. I’ve booked a 1day session at Upper Gilwern quarry with an overnight stay. Daylight hours and check in / out times mean that I will only have a limited 1 day max regardless of the weather. I want to maximise productivity and finds as I’m travelling a long way to get there. Does anyone have any specific guidance or tips for this location? Research has only provided general access descriptions and the fact that the chance of finds is high. But exactly where do I go in this quarry. I have no real idea on how big it is. Any help or specific pointers / tips would be greatly appreciated. Regards, Bob

Hey guys I need some help identifying these possible trilobites. Any information about which part of the trilobite the specimen is, species, etc would be appreciated. All of these specimens were found in Cincinnati, ohio in rocks from the Ordovician period. These 3 similar looking fossils are about 1 centimeter in length. This fossil is 3 centimeters in length. Showing front and back. This trilobite impression is 6 centimeters in length and 4.5 centimeters in width.

Howdy all, I cleaned up a small hash plate and found this curious formation.... I believe this is the cephalon portion of a trilobite. If it is, this is the largest T-bizzle I have found! Let me know your thoughts. I'm finding some really packed hash plates from my recent dig. Sorry again for the poor picture. I really need to get a camera. Anyone know how to sneak one of those by the wife? ;p

Hey so I recently went on a school trip to Caesar Creek to look for fossils. Most of what we we were looking for were small trilobites and ancient coral, but I found this long spine like thing in the ground and have no idea what it is... it was about the width of a fist.

Howdy All! Been a couple of months since I have posted anything. Work has kept me more than busy with travel. BUT, I wanted to share a quick day trip to my dig site yesterday in northern Cincinnati. I explored far left into the hillside I am excavating to see on the surface what Gastropods, Brachiopods and Bryzoa I could see and I was happily surprised that I found the mother-load! This area of my site was covered by a lot of growth and the runoff of water was less than in other areas I have been digging. I have attached a couple of pics and some real quick finds I cleaned up last night... sorry about the pic quality, I do not own a fancy camera. I love when I am lined up with conference calls and I can enjoy my hobby why listening to statistical analysis (actually mostly ignoring). I will try to save more pics in the comment sections. One specimen has me confused. I found a number of trilobite pieces throughout my day and collected around 25 hash plates with several in them. I have yet to clean them up. But pictured below (if it lets me) is what appears to be the bottom portion of a trilobite but I'm unsure.

these are three specimens collected in Fillmore County , Minnesota this summer. This is Ordovician. Beyond that, these were out of fallen rock and I can not narrow it down any more.I keep looking at them, not really sure I understand what they are. Soooooooooooooo feel free to comment on them. 1. Looks crinoidal but is full of pores. So bryozoan masquerading as a crinoid cup? Or bryozoan covered crinoid cup? 2. All I can think of is 2 brachiopod shells in apposition, but the linear structure in the middle confuses me. The hinge??

This past weekend, I had a chance to collect a well known roadcut outside of Clermont Iowa. The site is Ordovician in age and exposes the Clermont section of the Maquoketa Formation. one of the interesting pieces that I collected was this tiny trilobite. As you can see from the picture,There is not much to go on however the hypostome is preserved. I am hopeful the Trilobite will be complete and was wondering if anyone might know what species it is/could be. Any help is appreciated.

I can't seem to find an ID for this find. I believe this may be a siphuncle. What do you guys think? The "V" shaped sutures are really throwing me off. Has anyone seen a straight shelled cephalopod with this "V" pattern? Kinda neat how you can see how this was buried, preserving one side as it weathered the other. Then along came a dozen crinoids or so a used it as a nice base.

This fossil is from the Platteville formation in southern Wisconsin, which is Ordovician in age. It does not seem to be a compress spiral, but rather composed of separate pieces or plates that alternate on either side. At the tip there are two sections that are positioned in the middle rather than on either side like the rest of the sections seem to be. I put it under the microscope but there is not much finer detail besides the individual grains, so it does not seem to be a Bryozoan or Coral. If anyone has any leads they would be much appreciated. The scale is in centimeters.

A few french trilos preped during the summer 2018
elcoincoin posted a topic in General Fossil Discussion
During the summer i found time to empty a bit crates from the recent trilo hunts. Here come some of those recent prep. The samples come from 2 different sites which are only a few kilometers away one from the other. More or less orange ones from one place, black ones from the other. To start with, the emblematic Neseuretus tristani, most common trilos in our area. Those are second grade samples, but still, here they are : -
